G752VL notebook.
When I leave camper for a few days, I shut the notebook down (not sleep) and unplug it. Every time I get back after 4 days or so, and turn it back on, the battery will be down to in the neighborhood of 40%. The battery runs down at this rate prorated to however long I've had it down. Will be down to about 80% after 2 days and so on. What's going on here? Will the battery be ran down too far if I leave it down for a couple weeks?? It's not like I can take it out LOL.

That sounds more like sleep or maybe hibernation than it does as powered off.

How quickly does the battery run down if the laptop is powered on and not plugged in?

Do you have anything plugged into the USB ports? The laptop has the ability to charge things when it's powered off. Something like an aircard could draw power through a USB port.

Being that all reviews say the battery does not last but 1 to 4 hours, it seems about right when unplugged and running. I have unplugged all USB items and this continues to happen. Could the laptop not be shutting all the way down even though I choose "shut down" from the windows menu? I hit the space bar and the laptop does not wake up. I have to hit the power button and it shows the bios boot menu and then asks for windows pin.

Unless you have changed the default shut down to shut down, windows 10 default shut down is Hybrid Sleep IE fast start up here is how to fix that (http://www.tenforums.com/tutorials/4189-fast-startup-turn-off-windows-10-a.html) with that said if your seeing a BIOS boot sequence it does that seem to be from complete shut down. Asking for password or Pin would be normal for either. Otherwise if you battery is declining when actually turn off at the rate you mentions you could have a hardware issue. Some electrical short or defective battery or batteries. With the current battery configurations Lithium-ion all devices lose some power even when not turned on. Low self discharge (https://en.wikipedia.org/wiki/Lithium-ion_battery)

It's worth a try at disabling hibernation/fast start up, but it shouldn't make a difference. Hibernation copies the contents of RAM to the hard drive and then power it off like a normal shutdown. That's what you will see the POST process with hibernation and fast startup. But it's still worth a try because you just never know with Microsoft anymore.

My G752 has the same problem. I spent some time on google and it is definately Windows10 related. Multiple solutions are given, here's a few:

I have NOT tried these options (the drainage is not a big problem for me yet), but the reviews on the youtube video seems to be mostly enthousiastic.

Might be good to post here if it helps. Greetings.
